1. The USB device wake-up feature requires a power supply that can
provide 500mA on the +5VSB lead for each USB port. Otherwise,
the system would not power up.
2. The total current consumed must NOT exceed the power supply
capability (+5VSB) whether under normal condition or in sleep
mode.
4. USB device wake-up (3-pin USBPW1, USBPW2, USBPW3,
USBPW4)
Set these jumpers to +5V to wake up the computer from S1 sleep
mode (CPU stopped, DRAM refreshed, system running in low power
mode) using the connected USB devices. Set to +5VSB to wake up
from S3 and S4 sleep modes (no power to CPU, DRAM in slow
refresh, power supply in reduced power mode).
The USBPWR1 and USBPWR2 jumpers are for the rear USB ports.
The USBPWR3 and USBPWR4 jumpers are for the internal USB
headers that you can connect to the front USB ports.
